Long-term behaviour of concrete in water saturated media - Experimental and modelling approach

Abstract

In the context of the nuclear long-lived radioactive waste management, cement-based materials are currently used for waste encapsulation and containers development. Such materials are also likely to be used for engineered barriers in deep repositories. Various types of cement - CEM I, CEM V - have been currently studied, mainly to evaluate materials long-term durability. Studies have been performed on the leaching behavior of hardened cement pastes based on these cements. The effect of temperature is taking into account. Leaching experiments for 25 deg C, 50 deg C and 85 deg C were carried out with a standard test developed at CEA. Experimental results were analyzed and calculations were made to estimate calcium fluxes and degraded thicknesses. Experimental and modelling results were compared. (authors)
